• I'm confused why the first example does print the nil values, but the latter does not.
  Aren't these tables the "same"?

  1. local t = {nil, nil, 3, 7, nil, 4} 
      
     print(#t) -- 6
     print(unpack(t)) -- nil, nil, 3, 7, nil, 4

  2. local t = {}
     t[3] = 3
     t[4] = 7
     t[6] = 4
      
     print(#t) -- 0
     print(unpack(t)) -- nil

  I was always thinking that table.unpack can't iterate over "holes" in the same way as an ipairs-loop
  (I'm not a programmer, and I don't know what's the proper terminology)
  
  
• On another note, I'm also wondering about this (4 months old) post from Lur,
  concerning tables with a nil value at the end of a table

  Originally Posted by Lur Thanks a lot. But why local t1 = {1, 2, nil, "wwew", nil, 3} -- #t1 = 6 local t2 = {1, 2, nil, "wwew", 3, nil} -- #t2 = 2 What's wrong with all of that? Why tables with a nil as the last value are truncated to the first nil occurrence while with any non-nil end are counted correct?
